4941-77-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4941-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4941-77:
(6*4)+(5*9)+(4*4)+(3*1)+(2*7)+(1*7)=109
109 % 10 = 9
So 4941-77-9 is a valid CAS Registry Number.

Process for the preparation of 11(12)-pentadecen-15-olides

-

Page/Page column 7-8, (2010/02/05)

A process for the production of 11(12)-pentadecen-15-olide compounds (I) from 1-hydroperoxy-16-oxabicyclo(10.4.0)hexadecene (DDP-OOH) in the presence of a copper (II) compound and a diluent comprises distillation of an azeotrope containing water and the diluent during the reaction. Independent claims are included for: (1) a process for the production of DDP-OOH of formula (III) from 13-oxabicyclo(10.4.0) hexadec-1(12)ene (DDP) and hydrogen peroxide in the presence of acetic acid and 0.05-5 mol. % sulfuric acid (with respect to DDP); (2) a process for the production of 11(12)-pentadecen-15-olide compounds of formula(I) from 13-oxabicyclo(10.4.0)hexadec-1(12)-ene (DDP) comprising in a first step reaction of DDP and hydrogen peroxide in the presence of acetic acid and 0.05-5 mol.% H2SO4 (with respect to DDP) and in a second step reaction of DDP-OOH in the presence of a Cu-(n) compound and a diluent whereby an azeotrope containing water and the diluent are distilled off during the reaction. a, b = optional double bond.

SYNTHESE DE MACROLIDES PAR METATHESE.

Villemin, Didier

, p. 1715 - 1718 (2007/10/02)

Two syntheses of macrolides via olefin metathesis are presented.The first (A) involves preparation of ω-hydroxyacid 6 or 9 by metathesis followed by cyclisation, while the second (B) involves macrocyclic ring closure by metathesis of a ω,ω'diunsaturated ester 12.
